2011 Chev Aveo Thermostat Housing and Cooling Fan Resistor Replacement pt2

[@DrGonzo0001]

Just ordered me a new resistor also. I am having an issue with my thermostat running fine then it will jump to 3/4 temp and sometimes red line,but as soon as it hits the red line it jumps back down to running temp/halfway mark on thermostat. Great vid thanku for the detailed explanation of everything you were doing.

[@DrGonzo0001]

Forgot to mention it was doing this before i changed the thermostat housing. I was thinking a sticking thermostat was my issue. To me for it to jump back down from red line to running temp the high speed fan is kicking in but im not getting the low speed fan to kick on to maintain the running temp. Right? I dont lose coolent and the car runs great no check engine no slow down when the temp spikes happen.

Hi! Did you manage to fix it? My car is doing the exact same thing

@@DrGonzo0001 i wanna know if this works

[@DrGonzo0001]

Did not work. The eco tech engines are straight rubbish. Got rid of the car a while back. Sorry for not being able to help.

[@michealthaarchangel5088]

I'm going to replace that resistor I've been thru hell trying to figure out why it was overheating and the a/c not working thanks a lot. I'll let you know if I get good results thx.

[@DrGonzo0001]

Its been a month. Did it work?

hi there master chevy aveo 2009 seeing you awesome work have the seme issue only when reach 230F of temperature hi fan comes on but never low fan dropping resister when test is supposed to have ground or current? mine shows ground whit test light it will be awesome if you reply boss thanks

[@PhillipBailey]

The dropping resistor runs the fan on low speed. You can test it with an ohm meter for continuity or check for power going in and out of it when the low speed fan is supposed to be on. You can also put your test light across the resistor and if your test light turns on the resistor is open. good luck.

[@noelvillafane7747]

i really appreciate you doing that thanks mr philips

[@ecarroll3723]

I went to the parts store {Napa) and they said that the Dorman part number you provided cross reference is for the 1.4 and 1.8 that's in Chevy Cruze and not for the Aveo 1.6.. So does it still work for the Aveo 1.6 as well?

[@PhillipBailey]

This engine is a code G and was only sold in Canada as far as I know. Sorry I don't know if it would work for your application.

[@ecarroll3723]

@@PhillipBailey Thank you for the quick response and answer.. How can I tell what code my 2011 Aveo is?

[@PhillipBailey]

@@ecarroll3723 the 8th character of the VIN from the left.

[@ecarroll3723]

@@PhillipBailey Okay, mine has a code B from what the VIN says.. So is there any way to find out if its doable or not?

[@PhillipBailey]

@@ecarroll3723 I can't tell for sure but it does fit a 2012 Sonic with a 1.6 according to the Dorman website.

[@George-tt4cm]

Did you install the Thermostat housing assembly just as it came or did you swap the sensors from the old one?

[@PhillipBailey]

Installed it as complete.

[@George-tt4cm]

@@PhillipBailey I installed it as it came, and I'm getting code P0597. I was thinking that maybe I needed to put in the sensors from the old thermostat housing.

[@PhillipBailey]

@@George-tt4cm Thats a code for the thermostat heating element. Did you plug it in? Here's the test procedure: 1. Check the EMS2 EF25 fuse in the underhood fuse block. It should be hot with the engine running. 2. Disconnect the engine coolant thermostat heater connector on the thermostat housing. 3. Test for 12 volts on the Orange/Black wire. 4. Test for a pulsed ground signal on the Brown wire while commanding the heater with a scan tool. 5. If no scan tool support, check the Brown wire from the heater to Engine Control Module (ECM) terminal 43 in the X1 connector for opens and shorts. Alternately you could plug in your old one and see if the codes clear. If so the new part is defective.

[@George-tt4cm]

@@PhillipBailey Thank you. I noticed that there is coolant leaking from the connection where the throttle body heater inlet pipe connects to the thermostat housing, it is the same issue I had with the old thermostat housing. It looks like the issue is the throttle body heater inlet pipe, it's not sealing correctly. I will put in the old thermostat to see if the code clears.

[@brentpitchford54]

I looked up that part said it’s for a Chevy Cruz.

[@thadonofdetroit7679]

What is the silver clip on the bottom of the housing?....my housing is leaking from there.

[@PhillipBailey]

I believe its a heater element.

[@echofiend3722]

Bruh. You didn't show the thermostat housing installation at all. Should have just titled the video "2011 Chevy Aveo Cooling Fan Resistor Replacement"

[@PhillipBailey]

Sorry but it's just 4 bolts to the head, two bolts to the pipe and some hose clamps. It's not that difficult.

[@ShyRage1]

@@PhillipBailey the quick release on top I'm having trouble removing. Would have been helpful to see in action

[@asarcik]

Can we baypass cooling fan resıstor? connect two wire eachother ?

[@PhillipBailey]

Yes but the fan will run at max speed when it's supposed to be running on low. It may also blow the fuse for low.

[@asarcik]

@@PhillipBailey So I did but Not fan work at all .İs my mistake is only connect two cable without ground under cables ? so no 5v referance and not work fan? clearly I only connect 2 cable eachother thats it.. I did use A/C and be cold my engine only...

[@PhillipBailey]

@asarcik the part you bypassed is just a resistor. The fan only runs when the temperature or ac pressure require it to. Are your fuses good? Is the car overheating?

[@asarcik]

@@PhillipBailey Yes engine warm. But I check all fan relays with a multimeter. I listen tick voice from relays. Thermostat still open and close. Iwant to try to say resistor connect on ground and circle a metal cover. I think changeable volt 12 from 5 or reverse make by that ground.

[@PhillipBailey]

@asarcik the resistor does not need to be grounded. It's simply power in and out. Is there power and ground to the fan motor?

[@meganmiller7351]

Is the cooling fan part of the housing for the thermostat?

[@PhillipBailey]

No completely different parts
